在CLI介面安裝license
Step 1 Install a license on the controller by entering this command:
①license install url
where url is tftp:// server_ip / path / filename .

Note To remove a license from the controller, enter the license clear license_name command. For example, you might want to delete an expired evaluation license or any unused license. You cannot delete unexpired evaluation licenses, the permanent base image license, or licenses that are in use by the controller.
使用license clear license_name 命令去移除license，不能移除超期的評估license，永久的base license，控制器正在使用的license

Step 2 If you are prompted to accept the end-user license agreement (EULA), read and accept the terms of the agreement.
②如果有要求接受EULA，接受該授權。

Note Typically, you are prompted to accept the EULA for evaluation, extension, and rehost licenses. The EULA is also required for permanent licenses, but it is accepted during license generation.

Step 3 Add comments to a license or delete comments from a license by entering this command:
license comment

Step 4 Save a backup copy of all installed licenses by entering this command:
license save url
where url is tftp:// server_ip / path / filename .
④license save url 儲存已安裝license的副本

Step 5 Reboot the controller by entering this command:
⑤reset system

Step 6 Follow the instructions in the “Viewing Licenses” section to see the status of the license you installed.
⑥選擇 Management > Software Activation > Licenses 去對應的license頁面檢視

Step 7 If the desired license is not being used by the controller, follow the instructions in the “Activating an AP-Count Evaluation License” section or the “Activating an AP-Count Evaluation License” section to change the license that is used by the controller.
